The growth pattern, toxicology and chromium bioavailability in 45 days grown Paragrass (Brachiaria mutica Forssk.Stapf) in response to applications of ionic Chromium (Cr+6) and chelate-assisted Cr+6 were undertaken. Root and shoot length of Paragrass significantly decreased with increasing concentration of Cr+6. Paragrass plants grown both in Cr+6 (300 ppm) and chelate(EDTA/CA)-assisted Cr+6 (300 ppm) showed noticeable decrease in root and shoot length, fresh and dry matters whereas ionic Cr+6 or chelate assisted Cr+6- EDTA/ Cr+6-CA stimulated growth at low concentration (10 ppm). Root phytotoxicity was highest (56%) in Cr+6-EDTA (300 ppm) treatment whereas shoot phytotoxicity was 36% in Cr+6 (300 ppm) treatment. High Cr accumulation was found in root (46.65... view more»
